The evaluation board for HMC374

I did not see a mention of the characteristic impedance used in the PCB layout for the evaluation board (600-00435). I used a calculator based on the stack layout and found it to be 75 ohms. Is that correct? I thought the norm is use 50 ohms. Is there a reason why it was chosen to be 75 ohms. Do you offer gerber files with 50 ohm characteristic impedance?
